asymmetric MOSFET definitions in the tech file "extract" section.
Corrected the nmos.tech.in file to put the resistance classes in
plane order, as otherwise the interpretation of which resistance
classes belongs to the transistor source and drain can get messed
up by the presence of buried contacts.
magic database derived layout of a cell that declares GDS_FILE
but for which the GDS file referenced cannot be found or read.
This will produce an incomplete GDS file instead of an apparently
good and complete GDS file that actually contains bad data. Also:
Added new command "random" that allows a random seed to be set,
for use with the GDS output when writing a full dump of a GDS
file. Otherwise, the output prefixes are always the same, which
defeats the purpose of adding the random prefix.
magic (version 6.3) and lightly edited it to make it compatible
with version 8.3. Edited the scmos/Makefile so that it installs
with the rest of the distributed tech files.
preproc.py script from another project. Had to further develop it to
get around the amazingly complicated preprocessor usage in the scmos
subdirectory. Needed to add handling of parameterized definitions;
could not figure out how to align the syntax used in scmos/extract_template
with any consistent syntax. Gave up and rewrote some of the contents of
extract_template to avoid the more ambiguous usage. All of this is to
support a completely deprecated scmos.tech. However, it does avoid both
the M4 and cpp preprocessors altogether. Also did auto-detection of
python3 in the configure script for use of the preproc.py preprocessor,
and applied the same preprocessor to the macro definitions.
distributed installations, where the immediate installation location
is different from the final installation location, but in the case
where it is not desirable to put the entire install hierarchy as a
subdirectory of DESTDIR.
label in a DEF file is on a layer that has not been properly
mapped to a magic layer. This would apply a negative index to
a TileType bitmask and crash the program. Also: Changed the
style and colormap slightly to make the via2 and via4 styles
more visible.
and incorrect call to cairo_set_source_rgba which is in an unused
function and has no effect except with versions of Tcl less than 8.6
where "load -lazy" is not available and unknown functions cause
immediate exit. Cleaned up remaining references to OpenGL in the
Cairo code, and updated the copyright and acknowledged Chuan Chen, who
coded the Cairo interface. No attempt yet to deal with memory leaks
caused by calling Cairo "create" functions without the accompanying
"destroy" functions.
the python preprocessor version, the techfiles and .magicrc file
will get the correct arguments, without affecting the use of CPP
in the configure script.
python3 preprocessor is captured in the variable MCPP, not CPP,
since CPP is meaningful to the make process. Also, the
MAGICDIR variable in the name needed to be escaped so that the
variable is not evaluated within the configure script.
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
